My p valve seal is already doubled, I had that one addressed already lol. It really may just be coming from somewhere minute in my tester. I built it myself. My motor was a leaky mess when I got it so I have literally addressed every possible leak site, even to the point of splitting the case and checking for cracks (as it looked like something grenaded in there in a past life). Both crank seals are brand new, p valve doubled, and more hours in leak down testing than I have spent riding it lol
